Norton Internet Security facts for kids

Norton Internet Security is a security program made by Symantec Corporation that protects computers from malware. It includes antivirus, firewall, e-mail filter, and phishing protection software. It also includes features like parental controls which can be downloaded as a add-on.

You can get it from a download, a box copy in a store, or from a company that is an OEM. Norton Internet Security and its sister product, Norton AntiVirus, combined, held a 61% antivirus market share as of 2007. Major competitors in terms of market share include antivirus products from vendors CA, Trend Micro, and Kaspersky Lab.

Norton Internet Security runs on Microsoft Windows and Mac OS X. Version 16.5.0.135 is the latest update available for Norton Internet Security 2009, made available for users encountering issues when updating to build 16.5.0.134. The latest Mac version is 4.0.

Windows edition

In August of 1990 Symantec acquired Peter Norton Computing from Peter Norton. Norton and his company developed various utilities, or applications for DOS. Symantec continued the development of acquired technologies. The technologies are marketed under the name of "Norton", with the tagline "from Symantec". Norton's crossed-arm pose, a registered U.S. trademark, was featured on Norton product packaging. However, his pose was later moved to the spine of the packaging, and later dropped altogether.

Product activation was introduced to Norton Internet Security 2004, addressing the estimated 3.6 million counterfeit Norton products sold. A alphanumeric code is generated to identify a computer's configuration, which ties in with the product key. Users are allowed to activate their product five times with the same product key. Spyware detection and removal was introduced to the 2005 version for Windows, with the tagline "Antispyware Edition". The tagline was dropped in later releases.

Existing users of the 2006, 2007, or 2008 versions can upgrade to the latest 2009 version without buying a new subscription. Upgrading will preserve the number of days left on a user's subscription.

Version 2006 (13.0)

Norton Internet Security 2006 debuted on September 26, 2005. The main graphical user interface, dubbed the Norton Protection Center aggregates all information in a central location. CNET reports the Norton Protection Center, while useful, attempts to advertise additional products and services from Symantec.

To help identify zero-day malware, Bloodhound technology disassembles and scans application code for possibly malicious instructions. Norton can revert Internet Explorer homepage hijacking attempts and block advertisements. Users are warned of unauthorized changes to Internet Explorer's homepage, and given an option to revert such changes. Advertisement blocking rewrites a website's HTML to prevent advertisements from being displayed. E-mail filtering scans POP3 mail for spam. It can be configured using either a blacklist or a whitelist. Users can also correct Norton's classification of e-mail on a individual basis. Parental controls, bundled with this release, allow users to block specific sites, block certain programs from accessing the Internet, and restrict newsgroup access. Norton can block the transmission of confidential information. Users can enter information which are not to be communicated via instant messenger, e-mail, or webforms.

CNET noted this version's noticeable toll on system performance, especially when opening files across a network or on a removable disk. Oli Warner also noted Norton's significant drag when opening or creating files, compared to similar offerings from different vendors. PC Magazine noted the program's lengthy installation time and weak spam filtering feature; valid e-mail messages were marked as spam and actual spam e-mail were not.

Windows 98 compatibility was dropped from this release. System requirements were Windows 2000 Service Pack 3 or Windows XP, 325 Megabytes of free hard drive space, a 300 MHz processor, and 256 MB of RAM.

Version 2007 (14.0)

The 2007 version was released on September 12, 2006. 80 percent of the code was rewritten, with the goal of reducing high system resource utilization. A tabbed interface allows users to access the Norton Protection Center and the program settings without separate windows open. Symantec also extended its Veritas VxMS technology, enhancing rootkit detection. VxMS allows Norton to detect inconsistencies among files within directories and files at the volume level. Phishing detection was introduced in this release for Internet Explorer. Norton checks sites visited in Internet Explorer against a blacklist and analyzes sites' code. Other features include a exploit scanner which looks at system components commonly hosting vulnerabilities, such as Internet Explorer settings. Supplementing the scanner, real-time exploit protection blocks attackers from leveraging common browser and application vulnerabilities. When possible, Norton will fix issues found; otherwise the user is warned of the vulnerability. A startup application manager allows users to prevent applications from launching at login.

E-mail spam filtering, parental controls, advertisement blocking, and the information filtering features were not bundled with this release to reduce performance impact and disk space requirements. Instead, the features are available separately in 2007 add-on package.

CNET reports mixed results in performance testing; however gains were made over the 2006 version. Warner also noted the 2007 version's reduced impact on system performance, compared to the 2006 version. Similar to the prior version, spam filtering module misidentified valid e-mail and missed actual spam, according to PC Magazine.

Windows 2000 compatibility was dropped from this release. Compatibility with 32-bit editions of Windows Vista was introduced later in this release with a patch from Symantec. When installed in Vista, 350 MB of free space, an 800 MHz processor, and 512 MB of RAM is needed. When installed in Windows XP, 350 MB of free space, a 300 MHz processor, and 256 MB of RAM is required.

Version 2008 (15.0)

The 2008 version was released on August 28, 2007. New features include SONAR and the Norton Identity Safe. SONAR was designed using technologies Symantec acquired from WholeSecurity. The Identity Safe supersedes the information filtering function, storing webform information and can fill such forms. The information filtering feature is still available in the 2008 add-on package, and can be used in conjunction with the Identity Safe.

Phishing protection now integrates with Mozilla Firefox as well as Internet Explorer. The startup application manager was dropped from this release. Advertisement blocking was dropped from this release's add-on package.

When installed in 32-bit editions of Windows XP Service Pack 2, 350 MB of free space, a 300 MHz processor, and 256 MB of RAM is required. Support for 64-bit editions of Windows Vista was added in this release. 350 MB of free space, a 800 MHz processor, and 512 MB of RAM is required.

Version 2009 (16.0)

The 2009 version was released on September 8, 2008. Benchmarking conducted by PassMark Software highlights this release's 52 second install time, 32 second scan time, and 7 MB memory utilization. Symantec funded the benchmark test and provided scripts used to benchmark each participating antivirus software.

A single main interface replaces the tabs found in prior releases. New features include Norton Insight which whitelists files based on reputation, cutting scanning time. Virus signature updates are now delivered 5 to 15 minutes, supplementing the reliability tested updates issued by Symantec every several hours. However, such updates may incorrectly identify files as malicious, and users can elect not to receive those updates. Spam filtering was reintegrated in this release. The add-on package now includes information filtering and parental controls. The exploit scanner found in the 2007 and 2008 versions was dropped from this release.

System requirements call for a 32-bit edition of Windows XP, a 300 MHz processor, 256 MB of RAM and 200 MB of free space. When installed in a 32 or 64-bit edition of Windows Vista, an 800 MHz processor, 512 MB of RAM, and 200 MB of free space is required.

Notable new features include the integration of Norton Safe Web, a web rating service. Safe Web blocks access to malicious sites. Additionally, search results from major search engine, such as Google, are color coded for safety (green for safe site, yellow for possibly unsafe site, red for dangerous sites, and gray with a white question mark for untested sites). The toolbar redirects queries to the Ask.com search engine, however does not share code with the Ask.com toolbar.

Norton Internet Security version 1.0 for Mac was released November 1, 2000. It can identify and remove both Windows and Mac viruses. Other features include a firewall, advertisement blocking in the browser, parental controls, and the ability to prevent confidential information from being transmitted outside the computer. Users are prompted before such information is able to be transmitted. The incorporation of Aladdin Systems' iClean allows users to purge the browser cache, cookies, and browsing history within Norton's interface. Operating system requirements call for Mac OS 8.1. Hardware requirements call for 24 MB of RAM, 12 MB of disk space, and a PowerPC processor.

Version 2.0 also ties in with the WHOIS database, allowing users to trace attacking computers. Users can inform network administrators of the attacking computers for corrective actions. When running under Mac OS 8.1 or 9, a PowerPC processor, 24 MB of RAM, and 25 MB of free space is required. Under Mac OS X 10.1, a PowerPC G3 processor, 128 MB of RAM, and 25 MB of free space is required.

The subsequent release, version 3.0, maintained the feature set found in version 2.0. The firewall now allocates internet access as needed rather than relying on user input using predefined rules. Compatibility with OS 8 was dropped. When running under OS 9.2, a PowerPC processor, 24 MB of RAM, and 25 MB of free space is required. Under OS X 10.1.5 through 10.3, a PowerPC G3, 128 MB of RAM, and 150 MB of free space is required. However, version 3.0 is not compatible with OS X 10.4, or "Tiger".
